COMBINATION HOSE NOZZLE Filed Feb. 14, 1964 INVENTOR. Pa/p/I L Dav/o United States Patent 3,241,773 COMBINATION HGSE NOZZLE Ralph L. Travis, R0. Box 118, Sidney, Iowa Filed Feb. 14, 1964, Ser. No. 344,878 1 Claim. (Cl. 239436) My invention relates to a combination hose attached nozzle.

An object of my invention is to provide a combination nozzle which will effectively provide a fog arrangement, or a straight stream arrangement, or a spray arrangement.

A further object of my invention is to provide an arrangement which can be readily manually manipulated to provide any of the above conditions.

A further object of my invention is to provide a special arrangement whereby the device can be used for any of the above mentioned purposes without in any way removing or replacing any of the parts.

A further object of my invention is to provide a relatively simple arrangement which can be conveniently carried by the fireman and which is not large or bulky.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

FIGURE 1 is a longitudinal cross section of my nozzle,

FIGURE 2 is a forward view of FIGURE 1,

FIGURE 3 is an enlarged detail of a portion of the fog forming arrangement,

FIGURE 4 is a plan view of FIGURE 3, and

FIGURE 5 is a sectional view of FIGURE 1 taken along the lines 55 thereof.

My invention contemplates the provision of a readily changeable and adjustable device which when fighting a fire, will provide means for instantly shifting the unit to accommodate a variety of conditions.

In describing my invention I have used the character 11) to designate a hose coupling which is attached to the end of the fire hose, and I have used the character 11 to designate a substantially cylindrical member having the threads 12 which engage the threads of the member 10, the character 13 indicating an annular gasket.

I have further used the character 14 to indicate a further cylindrical member threadably engaged at 15 with the intermediate portion of the member 11, the character 16 indicating gaskets.

The member 14 includes a frusto-conical surface 17, and the character 18 indicates a series of equally spaced radially positioned circular openings extending from the central portion of the member 11 outwardly, and the character 19 indicates a pair of spaced annular grooves which grooves merge with the openings 18 as shown clearly in FIGURES 3 and 4.

The character 20 indicates a further annular gasket against which is tightly screwed the coupling portion 21 of the further member 22, the character 23 indicating a further gasket.

The member 22 includes the threaded end at 24 which is adapted to threadably engage the threads in the further member 25 having the opening 26, and attached to the member 22 at 27 are the bars 28 which are secured to the centrally positioned portion 29, and threadably engaged with the portion 29 at 30 is the rod 31, the character 32 indicating securing nuts,

The rod 31 terminates in a tapered valve member 33 having the flat disc portion 34, and the character 35 indicates a cylindrical hollow portion which is provided in the member 25, having the longitudinally positioned cylindrical wall 36.

3,241,773 Patented Mar. 22, 1966 The character 37 indicates a tapered or further frustoconical surface which is flared outwardly as at 38, the character 39 indicating the forward opening.

Positioned circumferentially about the member 25 and communicating with the surface 38 are a series of equally spaced openings 40.

The character 41 indicates a further sealing ring, and it will be noted that the space adjacently to the bars 28 will be open and will provide a free passage of the water into the member 25.

The nozzle is operated in the following manner. In case it is desired to provide a fog when fighting a fire, and which fog will be provided in a substantially hollow conical shape, the member 14 is rotated, FIGURE 1 showing the member 14 during the fogging position since the left hand sealing ring 16 will uncover the openings 18, this ring 16 normally effectively sealing the openings 18 when not in use. The water which enters into the passage-way 42 will be ejected out of the openings 18 and toward the frusto-conical surface 17, the water being ejected in the form of a fog for the following reasons. As the water impinges against the solid portions 43 (see FIGURE 5 or where the space at 43 is smaller than the spaces at 44, the effect will be that of a series of tiny wedges between each hole 18 which wedges will break up the water into a fine spray or fog, and also when the streams of water pass into the annular grooves 19, the fog forming effect is still further increased and when this fog is directed along the surface 17 a cone-shaped protecting fog is thereby provided, whereupon the fireman can then advance into the fire.

FIGURE 1 illustrates the valve member 33 seated against the opening 45 whereupon the forward end will seal the water; however when it is desired to provide a straight stream the member 25 is rotated on the threads 24 whereupon the opening 45 will be unsealed, and the water will be directed by the wall 36 into a straight stream passing directly out of the unit.

However when it is desired to provide a spray cone of water, the member 25 is rotated toward the member 14 still more, until the valve members 33 and 34 will be positioned exteriorly of the cavity 35 thereby allowing the water to pass along the outwardly tapered surface 37 whereupon the water will flow in the form of a spray cone, and the effect of the openings 40 will be such as to provide an air intake into the fluid stream.

As a result of the foregoing description it will be noted that the unit can be used to provide any of the types of conditions required in fighting fires, and merely by the use of simple manual operations, etc.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be reason-ably included within their scope.

I claim as my invention:

A combination hose nozzle comprising a cylindrical tube member, means for attaching a water carrying hose to said cylindrical tube member, said cylindrical tube member having a plurality of radially positioned openings communicating from the interior of said tube member to the exterior thereof, said openings being relatively closely spaced to thereby provide small wedge-like formations in said tube member between said openings, a cylindrical adjusting member threadably engaged with said tube-like member, said adjusting member having a frusto-conical surface against which a fog-like mist provided in said openings will impinge, and be directed in a cone-like formation, said tube-like member including a pair of longitudinally spaced annular grooves merging radially with said openings, a further cylindrical member attached to said tube-like cylindrical member, a valve member attached within said further cylindrical member, a forwardly positioned substantially cylindrical nozzle member threadably engaged with said further cylindrical member, said forwardly positioned nozzle member having a longitudinally positioned cylindrical cavity, said valve member including a sealing portion and a disc portion, said cavity providing a straight stream when water is confined within the peripheral limits thereof, said forwardly positioned nozzle member including a centrally positioned outwardly flaring frusto-conical surface, a plurality of radially positioned openings communicating to said frusto-conical surface to provide a cone-like spray when said forwardly positioned nozzle member is rotated to move away from said valve portions to allow water to pass along said frusto-conical surface.
